Drives & Pulleys - Performance Pulleys & Belt Tensioners

Optimize your engine's accessory drive system with our range of performance pulleys and belt tensioners designed for Australian V8 conversions, street machines, and custom builds. From lightweight aluminium pulleys to adjustable tensioners and Gilmer drive systems, we stock everything you need for reliable power transfer and reduced parasitic drag.

Drive System Selection Guide

Underdrive vs Overdrive Pulleys: Underdrive pulleys slow accessories 15-25% to reduce parasitic drag and free up horsepower. Best for racing and performance street cars. Overdrive pulleys speed up alternator for increased charging output in vehicles with high electrical loads (electric fans, fuel pumps, audio systems).

Pulley Material: Aluminium pulleys are lightweight and reduce rotating mass but may not be suitable for supercharger or high-load applications. Steel pulleys are heavier but provide maximum strength for forced induction and extreme applications.

Gilmer vs V-Belt: Gilmer (toothed belt) systems provide positive engagement without slippage, ideal for racing and high-RPM applications. V-belt systems are traditional and work well for street rods and classic builds requiring period-correct appearance.
